Original MT3 version is not placing pending orders. Because it was programed to trade manually using alert and chart. The same with indicator. It was not programmed for trading. Because it is not difficult to place pending orders manually. And this EA may be used to produce the trading signals to other people.

Somebody converted this MT3 version into MT4 without any changes (as is).

But later on this MT4 version was improved to place the pending orders. But this improved version seems having the bug because it is placing two pending orders instead of one (I checked now).
